perf tools: Default to 1 KHz auto-sampling freq events
Use auto-freq events by default in perf record and
perf top.
This allows more consistent hardware event sampling,
regardless of the intensity of the underlying event.
It also keeps us from over-sampling on larger/busier
systems.
(also make surrounding initializations more consistent)

x86: EDAC: MCE: Fix MCE decoding callback logic
Make decoding of MCEs happen only on AMD hardware by registering a
non-default callback only on CPU families which support it.
While looking at the interaction of decode_mce() with the other MCE
code i also noticed a few other things and made the following
cleanups/fixes:
- Fixed the mce_decode() weak alias - a weak alias is really not
good here, it should be a proper callback. A weak alias will be
overriden if a piece of code is built into the kernel - not
good, obviously.
- The patch initializes the callback on AMD family 10h and 11h.
- Added the more correct fallback printk of:
No support for human readable MCE decoding on this CPU type.
Transcribe the message and run it through 'mcelog --ascii' to decode.
On CPUs that dont have a decoder.
- Made the surrounding code more readable.
Note that the callback allows us to have a default fallback -
without having to check the CPU versions during the printout
itself. When an EDAC module registers itself, it can install the
decode-print function.
(there's no unregister needed as this is core code.)
version -v2 by Borislav Petkov:
- add K8 to the set of supported CPUs
- always build in edac_mce_amd since we use an early_initcall now
- fix checkpatch warnings

fujitsu-laptop.c:(.exit.text+0xbe37): undefined reference to `led_classdev_unregister'
fujitsu-laptop.c:(.exit.text+0xbe53): undefined reference to `led_classdev_unregister'
It happens because the new INPUT_WINBOND_CIR driver relies on new-leds
infrastructure - but does not select it in drivers/input/misc/Kconfig.
But it selects LEDS_CLASS, which confuses a number of other drivers into
thinking that all the leds infrastructure is in place.
Fix this by selecting NEW_LEDS as well, like similar drivers do.
Eventually, this whole leds infrastructure complexity should be
cleaned up, it's been going on for years.

x86: mce: Use safer ways to access MCE registers
Use rdmsrl_safe() when accessing MCE registers. While in
theory we always 'know' which ones are safe to access from
the capability bits, there's a lot of hardware variations
and reality might differ from theory, as it did in this case:
http://bugzilla.kernel.org/show_bug.cgi?id=14204
[ 0.010016] mce: CPU supports 5 MCE banks

So WARN_ONCE() instead of crashing the box.
( also fix a number of stylistic inconsistencies in the code. )
Note, we might still crash in wrmsrl() if we get that far, but
we shouldnt if the registers are truly inaccessible.

modules, tracing: Remove stale struct marker signature from module_layout()
Linus reported this new build warning:
kernel/module.c:2951: warning: ?struct marker? declared inside parameter list
kernel/module.c:2951: warning: its scope is only this definition or declaration, which is probably not what you want
Caused by:
fc53776: tracing: Remove markers
module_layout() is an artificial symbol with 'significant' symbols
listed in its argument list so that it gets a proper argument types
signature that modversions can pick up to decide whether a
module is version-compatible or not. If these dont match then we
wont even look at a module.
Remove the stale marker symbol.
